Question

If one angle of an isosceles triangle is 124 degree find the other angles images

Answer 1

Answer:- 28 degree

Refer the attachment for the steps and figure.

Answer 2

Hence each of the base angle is 28°

Step-by-step explanation:

Given:

Let ABC be an isosceles triangle.

Let vertex angle = ∠A = 124°

Let each of the base angle = ∠B = ∠C =  x  (base angles are equal in isosceles triangle)

Now,

∠A + ∠B + ∠C = 180°  (angle sum property)

124°  + x + x = 180°  

2x = 180° - 124°

⇒ 2x = 56°

⇒ $x = \frac{56}{2}$

⇒ x = 28°

Hence each of the base angle = 28°
